PC) RTA B LE STRAW-STACKER.

SPECIFICATION forming part of Letters Patent No. 681,175, dated August20, 190 1.

Application filed June 4, 1901. Serial No. 63,127. (No model.)

zen of the United States, residing at Seymour,

in the county of Wayne and State of Iowa, have invented a new and usefulPortable Straw-Stacker, of which the following is a specification.

My object is to provide a portable haystacker that can be readilyadjusted for building large stacks upon a broad base and also forbuilding stacks varying in diameter and height.

A further object is to detaohably connect the different parts, so theycan be compactly stored away when not in use and readily connected asrequired for practical use.

My lnventionconsists in the arrangement 1 and combination of a portableframe, a post pivotally connected with the base of the frame, and acrane-arm fixed to the post, as hereinafter set forth, pointed out in myclaims, and illustrated in the accompanying drawings, in which- Figure 1is a side elevation showing all the parts connectedas required forhoisting and i delivering hay upon a stack. Fig. 2' shows .the pivotedpost detached from the top of the frame and inclined as required to showthe manner of raising and lowering the cranearm and post.

Fig. 3 is an end view. The letters A and A designate parallelbase-pieces of the frame in the form of runners adapted for sliding uponthe ground, as

3 required to facilitate the movement of the machine from place to placewithout taking it apart.

B and B are uprights detachably fixed to each one of said parallelbase-pieces by means of screw bolts and nuts, and the top ends of thesaid uprights are also detachably bolted together.

and C are cross-bars resting upon the base-pieces A and A and detachablybolted to the uprights B and B D and D are stay-pieces detachably boltedto the end portions of the cross-bar G and also jointly and detachablybolted to the center of the cross bar 0 A rigid portable frame is thusproduced that can be readily taken apart at pleasure. The bolt D thatextends through the overlying ends of the stay-pieces and thecross-piece G has an eye,

andfis a pin that has a swivel connection with the eye of said bolt.

II is a post and to its lower end is fixed a metal plate H and the endsof the plate extend at right angles and have coinciding perforations toadmit the pin 11 as required to pivotally and detachablyconnect thelower end of the post with the port-able rigid frame. Hinge members Jare fixed to the top of the post, and a corresponding hinge member J isfixed to one of the uprights of the frame in such a manner that the topof the post is detachably hinged to the frame by simply inserting apintle J 3 in the hinge members. An elbow-shaped plate K is pivoted tothe post above the upper hinge member J in such a manner that in itsnormal position it will overlie the head of the pintle and keep the postsecurely hinged to the frame. Acranearm L is detachably fixed to the topof the post by means of a bolt and supported by stay-pieces L,detachably bolted to the central part of the post and the central partof the arm. A rope M is extended over direc- (ion-pulleys attached tothe frame, the pivoted post, and the free end of the crane-arm in such amanner that a hay-fork may be attached to one end of the rope and ahorse hitched to the other end, as required to operate the hay-stacker.v

Ropes N are attached to the sides of the pivoted post H and weights Pfixed to the ends of said ropes in such a manner that when the ropes areextended over pulleys R, fixed to the uprights of the frame, they willaid in retaining the post upright and balanced, and when one of theweights is placed upon the ground the other one will aid in swinging thepost and crane-arm in the direction it is desired to have it move whencarrying a load. When the post is unhinged from the top of the frame andthe two weights are suspended upon the hooks fixed to the uprights ofthe frame, the two weights will aid in retaining the swinging arm andpost in a vertical plane and also aid in pulling the postinto aperpendicular position,as required for restoring its hinged connectionwith the top of the frame.

It is obvious a person can readily climb to the top of the frame forremoving and replacing the pintle J as required for unhinging andrehinging the post to the frame whenever desired.

Having thus described the construction, arrangement, and combination ofthe different parts of my invention, its practical operation and utilitywill be readily understood by persons familiar with the art to which itpertains, and

What I claim as new, and desire to secure by Letters Patent, is

1. In a straw-stacker, a portable frame, a post havinga crane-arm boltedto its top end portion, stay-pieces bolted to the central part of thepost and the central part of the arm, a metal strap fixed to the lowerend of the post and its end extended at right angles and provided withcoinciding pin-holes,a pin swiveled to the frame and extended upwardthrough said pin-holes, a hinge member fixed to the top of the-frame andtwo hinge members fixed to the top end portion of the post, a pintleextended down through the perforations in the hinge members and anelbow-shaped plate pivoted to the post to engage the head of thepintle,all arranged and combined to operate in the manner set forth forthe purposes stated.

2. In a hay-stacker, a frame having fixed hooks on its uprights, a post,having a fixed crane-arm at its top, pivoted at its lower end to thecenter of a cross-bar fixed to the frame, ropes fixed to the post andweights fixed to the ends of the ropes, arranged and combined to operatein the manner set forth for the purposes stated.

3. A portable hay-stacker comprising a portable frame, a post pivotallyconnected with the center of a cross-bar at the lower end of the frameand detachably hinged to the top of the frame, a crane-arm fixed to thetop of the post, ropes fixed to the post and weights fixed to the endsof the ropes, hooks fixed to the uprights of the frame for connectingthe ropes and weights with the frame, pulleys attached to thecrane-arm,-the post and the frame and a rope extended over said pulleys,all arranged and combined to operate in the manner set forth for thepurposes stated.
